New analytical model for local heat flux density in the mold in continuous casting of steel

In this article, a model representing local heat flux density in the mold in continuous casting of steel is presented. This model is a modification for empirical model of Schwerdtfeger. A new parameter is defined as LHTCz (longitudinal heat transfer coefficient). The multiplication of LHTCz to total increase of the cooling water temperature (ΔTwT) leads to a new model for local heat flux density. Since ΔTwT is a measurable parameter, the present model can be used in on-line controlling of continuous casting process. Results of the present model were compared with the experimental data and a good agreement was seen. Also it was shown that present model can be used as a boundary condition in solidification numerical modeling.
